The modular debris rack permits installation and removal the modular debris rack, rack frames, and removal and reinstallation of rack frame bar components without tools, and simple removal or replacement of individual rack frame components either without tools or with a minimal amount of tools. The modular debris rack frame can be made from any materials such as steel, aluminum, fiberglass, plastics, rubber, or any combination thereof, and other elements to any required size or shape installed either individually or by grouping and can be installed at any angle or orientation.

FIELD OF THE INVENTION

The present invention relates to a modular debris rack installed in the marine and/or underwater and other environment for preventing foreign or other materials from entering into fluid, water intake, inlet, or outlet equipment and facilities, flow control systems, hydraulic structures, waterways and marine structures and facilities either not submerged, partially submerged, and/or completely submerged.

More specifically, it relates to a means for preventing foreign or other materials from entering into fluid, water intake, inlet, or outlet equipment and facilities, flow control systems, hydraulic structures, waterways, marine, and other structures and facilities and/or retaining foreign or other materials at or within such structures and waterways being comprised of one or plurality of linear or curved upper, lower and/or side to side rack frames, and/or optionally installed intermediate rack frames with solid or tubular round, square, rectangle, angled, or other shape removable rigid rack bars, and/or removable flexible rack cables, cords, chain, rope, or other type flexible longitudinal structures to fit the desired rack orientation and spacing installation requirements. The modular debris rack permits rapid removal and reinstallation of the modular rack, and rack bar components without tools or with minimal tools and simple removal or replacement of individual rack frame components without tools, and permits rapid access to flow control devices and other equipment and facilities located behind the modular debris rack for inspection, maintenance, repair and replacement. The modular debris rack frame can be any size and shape, and be single or multi-sided, made from any semi-rigid and/or rigid materials such as steel, aluminum, fiberglass, plastics, and other elements to any required size or shape installed either individually, grouping, stacking, or layering and can be installed at any angle or orientation.

BACKGROUND OF INVENTION

Debris racks, trash racks, and other such equipment in the marine and other environments are prevented from rapid removal and reinstallation in whole and in part due to being constructed as a unit, and being fixed as a unit to equipment, structures, and other facilities installed by welding, embedment, riveting, bolting, and other respective permanent and semi-perminant joining and connection methods thereby preventing the removal and reinstallation of the unit, its parts, or individual elements of the constructed unit and substantially preventing and limiting efficient removal and replacement of the unit in whole and/or in part. For these reasons, there is a need in the art for a new system to permit a modularly constructed debris rack device for modular, rapid disassembly, removal, and reinstallation of its components which overcomes the above disadvantages described.

DETAILED DESCRIPTION OF THE INVENTION

In the absence of prior art and in order to eliminate prior restrictions and limitations, the present invention has been devised for partial and complete modular assembly, operation, installation, removal, servicing, replacement, and reinstallation. The present invention relates to a modular debris rack installed in the marine, underwater, and other environments for preventing foreign or other materials from entering into fluid, water intake, inlet, or outlet equipment and facilities, flow control systems, hydraulic structures, waterways and marine structures and facilities either not submerged, partially submerged, and/or completely submerged. Existing equipment is prevented from rapid removal and reinstallation in whole and in part due to being constructed as a unit, and being fixed as a unit to equipment, structures, and other facilities installed by welding, embedment, riveting, bolting, and other respective permanent and semi-permanent joining and connection methods thereby preventing the removal and reinstallation of the unit, its parts, or individual elements of the constructed unit and substantially preventing and limiting efficient removal and replacement of the unit in whole and/or in part. For these reasons, there is a need in the art for a new system to permit a modularly constructed debris rack device for modular, rapid disassembly, removal, and reinstallation of its components which overcomes the above disadvantages described.

Referring now to FIG. 1, is an elevation view showing the position in this sample installation of the two rack frame component ends (3E1) and (3E2) in this case with upper and lower orientation in front of a sluice type flow control gate (1), installed in this example to a concrete control tower (2) by a selected quantity of mounting studs (3E1H) and (3E2H) in selected drilled holes in frame components. Two or more rack frame components may be used and oriented at any angle, and may be multi-sided to be installed on a variety of structure shapes and sizes. Mounting stud holes can be any size or spaced as desired. The pre-drilled spaced mounting holes allow for continued installation in the event that a mounting stud is prevented from being installed due to obstruction, localized structure defect, or other cause. In this event the installer simply moves to the next pre-drilled rack frame hole (3E1H) (3E2H) and continues with the installation of the mounting studs. This feature alone can save significant installation time through inherent installation fault tolerance.

Referring now to FIG. 2 is a plan view showing a sample installation of the modular rack frame (3E1-E2) to a curved structure (2) using mounting studs (4W) with a sluice gate type flow control device installed (1) to the structure. Other installations of this type example can be made on an irregular shaped, elliptical, curved, flat, offset, round, or other shape structures. Also shown is one of the variants to welded frame component construction using two end plates and bolted variable size brackets (3A), (3B), (3AB) with removable drilled frame end plates (5), (5FH). Also shown are drilled frame rod holes (3-4FH) for installation in this example of round frame rods. A plurality of other shaped rods or elongated structures functioning in similar capacity are also used to accommodate the removable bars which can be oriented in any linear or nonlinear position. Optionally installed hardware connected end plates (5FH) can be installed as a way to maintain equal or other spacing and orientation of two or more rack frames (3E1H-3E2H) during and after installation, increase structural rigidity, act as a solid side barrier so foreign objects do not penetrate the rack from the sides, and for estetictley pleasing and professional look. With numerous pre-drilled rack frame mounting holes (3-4FH) any number of anchor studs (4W) can be used within the limit of the quantity of number of pre-drilled holed to secure the rack frames to a structure. Partial width and full frame width rack frame brackets (3A-3B) can be used with hardware connected multi-element frames. Any number of rack frame brackets can be used within the limit of the quantity of number of pre-drilled holes in the rack frame backing plate to secure the rack frames to a structure. Rack frames can be one piece extruded, welded combined multi-element, fitted and hardware connected multi-element.

Referring now to FIG. 3, upper illustration is a longitudinal side section view of a welded combined multi-element rack frame shown in vertical orientation. In this optional frame configuration, a plurality of plates or frame components are joined by welding, fusing, adhesion, or other semi-permanent or permanent connection method in a configuration to support, contain, and guide the rack frame bars. The three components consist of a top rod pass through plate (2A), a backing plate which is typically secured to a structure by anchor studs or other hardware or mechanical device with the rack frame(s) attached to a structure either under tension with minimal tools, or studs installed as hanger hardware with rack frame(s) being hung from the hanger studs secured by keyed slots or similar such integrated or attached feature or accessory permitting the modular debris rack(s) and all components to be installed without tools, and the bottom rod pass through plate (2C). The middle illustration is a longitudinal side section view of an assembled combined multi-element rack frame shown in vertical orientation with a drilled upper rod pass through plate (2FH), a drilled backing plate typically used to secure the frame to a structure by anchor studs or other hardware or mechanical device (2E1H), a drilled bottom rod pass through plate (2FH) and an optional rod retention end plate (2D) which is secured to the top plate (2A) by a variety of means to cover the rod insertion holes once the rods have been inserted. The lower illustration is a longitudinal side section view of an assembled combined multi-element rack frame shown in vertical orientation with a drilled upper rod pass through plate (2FH), a drilled backing plate typically used to secure the frame to a structure by anchor studs or other hardware or mechanical device (2E2H), and a solid bottom rod retention/stop plate (4). In this configuration the rack rods pass through the upper frame top and bottom plates, pass through the upper plate of the bottom frame and seats against the inside surface of the bottom frame plate. Optionally, end plates may be installed at both upper and lower or opposing positions to retain the rack frame bars within the rack frame assembly. Typical rack frame bar guide hole patterns are shown with one rack frame having rod holes in two plates and one rack frame with rod holes in one plate. A plurality of rack frames with guide holes through two plates may be used.
